UNITED STATES HUGH W. SANFORD. OF KNOXVILLE. TENNESSEE.

RAILWAY GAR.

Application filed March 5, 1925.

To all w/m/n it may concern.

Be it known that I, HUGH W. Sanroun, a citizen of the United States, residin at Knoxville, in the county of Knox and tate of Tennessee, have invented a new and useful Improvement in Railway Cars, of which the following is a specification, reference being had to the accompanying drawing.

This invention relates particularly to such railway cars as are used in mines for hauling coal or ore.

The object of this invention is to produce a car of good construction and of lar e capacity for a given height above the ralls, to the end that cars used in mines hav n low head room will have the largest feaslb e capacity for that head room.

In the accompanying drawings,

Fig. l is a side elevation of a car embodying my improvement, parts being in section:

Fig. 2 is an end elevation of the same car;

Fig. 3 is a plan of a little more than onehalf of said car;

Fig. 4 is a bottom view of the part of the car shown by Fig. 3;

Fi 5 is an upright transverse sectlonon the line, 55, of Figs. 1, 3 and 4, looking toward the right;

Fig. 6 is an upright longitudinal section on the line, 66. of Figs. 3 and 4, lOOklIlg in the direction of the arrow;

Fig. 7 is an upright longitudinal sectlon on the line, 77, of Figs. 3 and 4;

Fig. 8 is a horizontal section on the line, R8, of Figs. 1 and 7;

Fig. 9 is an enlarged detail upright section on a part of the line, 5-5, 0 Figs. 1, 3 and 4, td more fully illustrate the axle and wheel structure;

Fig. 10 is a detail elevation showing a part ot one of the axle bearings;

Figs. 11 and 12, illustrate details of one of the wheel hoods;

Fig. 13 is an upright, transverse section on the line, 13 13, of Fig. 6.

Referring to said drawings, A, A are side sills. These are of channel-form with an upper and a lower flange, A, and with circular apertures, A", to receive axle bearings, D.

B. B are end sill structures joined to the ends of the side sills, A. These end sill structures are similar to the end sill structure of my United States Patent, No. 1,486,547, dated March 11, 1924. The chief Serial No. 13,280.

feature of this structure is a plate metal end sill formed b shearing a suitable blank from a steel plate and bending the blank to form an upright web, B and an upper flange, B, and a lower flange, B the flanges being used as a part of the coupling structure, as described in said Letters Patent. Each.end of said plate metal member is secured to the adjacent ends of the adjacent side sills by means of an angle piece, B. having one arm riveted or bolted to the web of the plate metal member and having its other arm lying in the channel of the side sill and riveted to the sill in the manner described in my said Letters Patent.

An I-beam, C, is placed midway between the side sills, A, and extended from the back face of one plate metal end sill member to the back face of the other of said members. At each side of the I-beam and at each end sill memberis an angle member, 0 having one arm riveted or bolted to the u right web of the plate metal member and aving its other arm resting in the channel of the I-beam and similarly joined to the web of said beam. This I-beam is positioned to reinforce the end sill structures to adapt said structures to better resist ulling strains and impact strains. This I- eam may also be used as a part of the means for supporting the car floor or bottom.

These drawings have been made from drawings for a car for a 44-inch gage track, the car having a bottom width (if 72 inches between the sidesills, and the car body havin a length of 10 feet, exclusive of the end sil and coupling structures.

' In each aperture, A in the side sills is seated an axle bearing, D, which surrounds one end of an axle, E. The bearing is cylindrical interiorly and exteriorly, and its outer end reaches through the ad acent aperture. A, and is integral with a base plate, D which lies against the outer face of the web of the side sill and between the flanges, A of said sill and is secured to said web by bolts or rivets, D The end of the axle abuts against the inner face of said base plate. Next to the axle bearing, D, is the axle boxing, F, which closely surrounds the axle and has an annular flan F surrounding the adjacent end of t e hub, G,

of the wheel, G. The inner end of the hearing, D, has teeth, D, which extend between corresponding teeth, F on the axle boxing, F. By this means, these two members mtarlock or inter-engage for holding the axle boxing against rotation. At the opposite end of the wheel hub, G the axle is surrounded by another axle boxing, H, which has a flange, H surrounding the adjacent end of the wheel hub. This axle boxing abuts against an annular shoulder, E, formed on the axle E. A set screw H extends through the axle boxing, H, and bears against the axle for holding the axle boxing immovably on the axle. Whether the axle or the wheel will turn depends upon the ratio of friction when the car is on a straight track and on a curved track.

Each axle and its axle bearings and axle boxings together form an axle structure.

The wheel hub, G is provided with any suitable bearing. The drawings show antifriction rollers, I, surrounding the axle within the hub. This part of the construction may be of ordinary form. At each end of the hub a pair of washers, J, surround the axle and bear against the adjacent axle boxing and take end thrust and end thrust wear and may be replaced. The axles, E, extend through apertures in the upright webs of the I-beams, C, those apertures being large enough to allow the passing of the annular flanges, E of the axles.

The bottom, K, of the car occupies the s aces between the side sills, A, and the end 5111 structures, B. and the I-beam, C, preferably at the level of the lower edges of the side sills and the end sill structures and the Lbeam. The bottom is supported as will be described further on.

The side sills form parts of the side walls of the car body. On the upper flange of each side sill rests a side wall section, L, which, in the form shown in the drawings, is wooden planking. Each such section is secured to the adjacentside sill by upright bars, L, lying against the outer face of said section and bent inward to lie against the outer face of the web of the adjacent side sill. Said bars are secured to the section, L, and to the side sill by bolts or rivets, L.

Each end sill structure forms a part of the end wall of the car. Above each end sill structure is an end wall section, L, having its outer face in the plane of the inner or back face of the plate metal end sill mem- 'ber. Angle members, L, rest on the upper flange, B, of the plate metal end sill member and are riveted thereto. Bolts, L, extend horizontally through said angle pieces and the wall section, L, and adjacent u right bars, L, which are applied to t e inner faces of the end wall section and extend downward through apertures K in the bottom, K, and have, their ends bent horizontally to form horizontal supporting arms, L, bearing against the lower'face of the bottom, K, and supporting said bottom. A bolt, L, extends through each arm, L',

and the bottom,-K, to secure the bottom and said arm firm] to each other.

7 The end wali section, L and the end sill structure together form the end structure of the car.

Each bottom plate has along the adjacent side sill an upward-directed flan e K which overla s the inner face of t e side sill. Along t e I-beam, each bottom plate is offset upward to form a horizontal flange, K, overlapping and resting on the adjacent lower flange of the I-beam. Each bottom plate is also shown supported from the axles, E, by hangers, K, extending over the axles and downward and suitably secured to the plate.

Because the bottom orfloor, K, is below the axles, E, the wheels must extend downward through the bottom. Accordingly at each wheel, the bottom has an opening, K large enough to receive the adjacent wheel and the axle boxings.

A hood, M, extends over the opening, K, and the wheel and the axle boxings and the bearing, D. This hood consists of oblique sides, M, having lower flanges, M, resting on the upper face of the adjacent bottom plate, K, and secured thereto by bolts, M The top, l\ of the hood is shown integral with the sides, M The end of the hood next the side wall has upturned flanges, M, which bear against the outer upright saddle plate. M, and are riveted to said plate. The lower part of the saddle plate, M is cut to seat on the bearing, D, and extend downward at each side of the bearing to the bottom, K. Along the upper part of the bearing, D, the saddle late is preferably provided withan inwar turned flange, M. At the opposite end of the hood there is a similar inner upright end plate, M, which has at its upper end a flange, M overla ping the end edges of the side and top 0 the hood and riveted thereto. The lower part of this end plate is cut out sufficiently to allow the plate to extend downward at each side. of the adjacent axle boxing, H. At each side of said opening, said plate is bent outward to form a flange, M resting on the bottom, K, and secured thereto by bolts, M. Along the upper part of the axle boxing, this end plate is bent away from the wheel to make a flange, M, resting like a saddle on the axle boxing. Thus the hood is given two saddle-like supports, one on the axle bearing, D, and the other on the axle boxing, H.

The hood being thus supported, it is adapted to give support to the part of the bottom, K, to which the hood is'attached. It has already been stated that the bottom s supported by the hangers, K, reaching downward from the axles to the bottom; add that the ends of the bottom are sup orted by the arms, L, of the upright bars, L.

It has also been explained that the side edges of the bottom lates are turned upward to form flanges, and K, the former overlapping and restin against the s de sills and t e other over appin and resting on the lower flanges of the I- ams.

The several parts of the hood are to be assembled and oined to each other to make the hood complete, ready to be set into position and have its lower edges secured to the bottom, K, by means of the bolts, M. It will be seen that this construction permits convenient detaching and removal ofthe hood.

The bearings, D, and the axles, E, are in a horizontal plane cutting the side 81118. The parts of the plates, D which are opposite the ends of the axles form abutments to take end thrust from the axles.
